The boiling point of water at sea level is 100 degrees Celsius. This temperature is the point at which water transitions from a liquid state to a gaseous state, known as steam. The boiling point can vary based on altitude and atmospheric pressure; at higher elevations, where pressure is lower, water boils at a lower temperature. This property of water is significant in various scientific, culinary, and industrial applications. Understanding the boiling point is essential for cooking methods, such as boiling and steaming, and for processes like distillation, where separating components based on boiling points is crucial.
